TYPE-WRITING MAcHlNE.

SPECIFICATION forming part of Letters Patent N0. 647,035, dated April10, 1,900.

Application led November 25, 1898. Serial No. 697,339. (No model.)

To all whom. t may concern:

Be it known that I, AUGUST SoHNEELooH, a subject of the Emperor ofGermany, residing at the city of New York, borough of Brooklyn, countyof Kings, and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is aspeciication, reference being had therein to the accompanying drawings.

My invention relates to type-writing machines; and its object is toprovide a rapid and accurate key-action for such machines, the parts ofwhich may be readily disconnected and put together again and which willadmit of the independent adjustment both of the printing-point and ofthe bearing of each type-bar.

To these ends my invention consists of a device for actuating thetype-bar from the movement of the keylever, comprising an auxiliaryleverand connecting-link, of a new journal or bearing for the type-bar, of anadjustable hanger for such journal, andof certain details inconstruction.

I attain the objects by the mechanism illustrated in the accompanyingdrawings, in which similar letters indicate similar parts throughout thevarious views.

Figure 1 is a side view of my device applied to a visible-writingmachine. Fig. 2 is a section on line-2,2 of Fig. l. Fig. 3 is a sectionon line 3 3 of Fig. l: Figs. 4. and 5 are detail views, respectively, ofthe hanger and heel of the type-bar, showing the bearing for suchtype-bar. Fig. 6 is a detail view of the auxiliary lever. Fig. 7 is asection on line 7 7 of Fig. 8, and Fig. 8 is a detail view of theconnecting-link.

The mechanism is shown in the drawings adapted to that class oftype-writing chines in which the writin g is visible to the operator.

A, J, and I indicate parts ofthe frame of` tively, to operate in theslotted bearing-openopening j, by means of which it is fulcrumed on atpin or bar j, supported in part J of the frame. The key-lever G isoperatively connected with said auxiliary lever F by means of pin 7L andopen slot f.

In providing means for operating the typebar from the movement of thekey-lever it is-important that the connecting mechanism be quick-acting,so that there should be the least possible amount of 10st motion betweenthe parts. I accomplish this in my device by making all the joints andbearings pivotal and not a combination of pivotal and sliding bearings.The key-lever G, Fig. l, is fulcrumed on rod t', supported by part I ofthe frame. O is a spring abutting against keylever G on knob 71. thereonand against screw P in frame I, whereby an adjustable spring tension ofthe key-lever is provided.. Said lever G is provided with pin h,operating in open slotf of lever F, so as to work said lever F upon itsfulcrum j as said lever G is worked upon its fulcrum. Connecting-link Ecommunicates motion from lever F to typebar D, being connected withthem, respectively, by the pivotal bearings c fand e d. The dotted linesshow'the position of the parts when the key II is depressed, the onlysliding motion of the action being an inappreciable amount of pin h inslot f It is also important that the several parts of the key-action maybe readily disconnected independently of the rest of the machine forVpurposes of cleaning, repairing, and the like.

I therefore have provided a new system or combination of open joints orbearings and a new split bearing for the type-bar.

Great difliculty has been encountered in producing a typewriting machinein. which the alineinent of the writing produced thereby is and may bemaintained accurate. A

Vcommon method of accomplishing this result is by changing the positionof the type d on type-bar D. As the type is soldered to the bar, such amethod of adjustment involves delay and. expense. By moving the journalIOO on the type-bar toward or away from the printing-point of the platenthe desired result may be accomplished. I provide for such adjustment ofsaid journal inthe following manner: Said journal is carried by thehanger comprising the parts K and L and means for uniting them. A slotis formed in said hanger by the cut-away portions 7a and Z,respectively, of the parts K and L. A setscrew Q-passes through thisslot, screwing into segment C and holding the hanger in position. Whenthe set-screw is loosened, the hanger may be raised or lowered, so as tobring type CZ into proper alinement. Grooves o in the hanger operatingwith slides or rails c on the segment may also be employed to givesteadiness to the hanger and guide it as it is being adjusted. It isalso important that the action of the type-bar be free from vibrationandaccurate, and at the same time it should be allowed to operate with aslittle friction as possible. I have provided a new journal embodyingthese features and means of adjusting said journal, whereby the properaction of each type-bar may be easily maintained as the machine becomesworn by use. My new journal is also dust-pi'ooF,\\-'l1ich is one of theprincipal features of my invention, and I do not limit myself to theparticular construction described-as, for instance, the grooves on theheel and the rings on the pieces K and L might be transposed withoutdeparting from my invention. I now proceed to describe said journal.

Referring to Figs. 2 to 5, inclusive, the heel D of the type-bar isextended so as to provide room on each side of said extension of theheel for similar circular grooves CZ", concentric with each other. Eachof the parts K and L is cut away, so as to leave on each a circular ribor ring Zo and Z, respectively, said rings being adapted to operate oroscillate one in each of said grooves CZ, and so as to form the onlypoints of contact between said extension ot' heel D and said parts K andL. Said parts K and L, I then place upon said extension of heel D, sothat ring Zr; fits in one of the grooves CZ" and ring Z in the other ofsaid grooves, and screw the parts together by screws n and n. The wholeis then attached in any convenient manner in its proper position onsegment C. Additional steadiness may be given this journal by providin gbearing-opening cZ" in heel D concentric with grooves d and similarbearing-openings in pieces K and L concentric, respectively, with ringsZc and Z and passing through the bearing-opening thus formed the typebarbearing-pin M, which is held in position by nut fm. It will readily beunderstood that a second leverage is thus obtained and that ,by theregulation of bolt-pin M the journal may be properly adjusted. From thissplit journal the type-bar D may also be readily removed.

The parts of the key-action may be assembled as follows: The type-barhaving been adjusted, the Hat pin e of the connecting-link E is insertedin the bearing-opening CZ of the type-bar and the flat pin e of saidconnecting-link is inserted in the bearing-opening f of the lever F, andthen the bearing-opening f ot said lever F is adjusted upon the iiat pinor bar j. The pin Zt ot the key-lever G is then placed in the open slotf ot' said lever F, and when the open bearing at the rear ot' saidkey-lever has been placed upon the rod t' the several parts will be heldin proper position by adjusting-spring O.

What I claim, and desire to secure by Letters Patent, is

l. In a key-action for type-writing machines comprising a key-lever, anauxiliary lever, an oscillating type-bar, and a connectinglink, themeans of rendering said parts readily separable frorn each other and themachine consisting of a split journal for the type-bar, slottedbearing-openings in said type-bar and said auxiliary lever cooperatingwith flat pins on said connecting-link, a second slotted bearing-openingin said auxiliary lever coperating with a at pin or bar on the frame ofthe machine, an open slot in said auxiliary lever cooperating with a pinon said key-lever and a half-open bearin g-openin g on said key-levercooperating with a pin or rod on said frame.
